Hi. Typically a 3ft fluorescent T5 is about 1,900 lumens. This fitting is 1,300 so it will be less bright. However, fluorescent tubes lose their efficiency and light output after a while so they don't always maintain the 1,900 lumens. It depends how old your current tube is and what light level you've got used to. Maybe try it and if not happy you can return it?
